As the exam officer pounded away at her ass, her thoughts just emptied out of her brain. She pictured she was somewhere else. It was a large field, and she was bent over a fence, with something heavy putting it's weight on her as it fucked her from behind. She didn't know what it was, and she didn't really care, but the thought of it all was guiding her towards an anally induced orgasm. As she got closer, she could feel the familiar pressure building up in her breasts again, and when she started to peak, they felt about ready to blow.
She pushed them into the fence hard, squeezing the milk out of them and the cock pushed her over the edge.
"MoooOOOOOOO" she bellowed. If it hasn't come from her own mouth, she would have assumed it was actually a cow that made it.
"What the fuck?! They're soaked! What the fuck did you do?!" The officer screamed, snapping Lucy back to the exam hall. She looked at the desk she was bent over, her milk saturating the student exams and even trickling off the edge. She turned to look back at the officer as he frantically buttoned his jeans back up, then stood upright so she could do the same, wiping away a glob of leaking cum before pulling up her jeans. Her own top was soaked through too, and she didn't have a spare.
"I'm gonna lose my fucking job! Get out! Get the fuck out of here you dumb cow!" He shouted at her.
Lucy felt more than embarrassed, saying nothing as she quickly grabbed her stuff and left, heading for the bathroom again to clean up once more.
Once she felt her butt had been sufficiently emptied, she caught a glimpse of her genitalia, and took a moment to prod around it. A puffy mound with a slit down the center now sat where her cock did previously. Out of curiosity, she slid her finger into the middle, getting as far as the second knuckle on her middle finger before hitting the end. She already felt soaked, so her finger slipped in and out gently with ease, eliciting slight moans as she did so. Someone else then entered the bathroom, locking themselves in the cubicle next door. Lucy quickly composed herself and left her own cubicle.
She stopped on the way out to check herself out in the mirror. She was a hot mess. She waa sporting the most obvious sex hair she'd ever seen, and her fleshy little ear flaps were sticking out the side along with her little white horns. He top was completely soaked through, giving a vague glimpse of her cleavage, and what a cleavage it was, close to bursting out of the (also drenched) bra she'd put on this morning. But it wasn't just her chest that had thickened more, her whole body had too. Her jeans felt extremely tight now, clinging to her body like leggings, especially so around her thighs, hips and ass. She even had a little bit of gut spilling out over the top. The poking out the back had grown even more, to a point she didn't think she could hide it any longer. The length of it felt the same as the rest of her skin, but the end still had the thick tuft of dark hair. She even felt shorter still, likely close to hitting the 5ft point now.
But besides the new animal features, she now looked completely feminine. A short, thick, busty kind of feminine, but she actually liked it. She was most taken by her new face, which had rounded out more since she'd last taken the time to examine it. She felt awkward blowing her own horn, but she she thought she was beautiful.
Once she was done mentally complimenting herself, she focuses on the problem at hand. The tests were ruined, but she couldn't really do anything about that now. Her clothes were also ruined, so perhaps going home to change was a good idea. If she was quick, she'd be back in time to meet up with Mike.
Mike...
The thought of Mike made her feel all tingly again. While she'd enjoyed getting her cum doses from Sam, Dennis, or the exam man, Mike made her crave something more. She didn't just want his cum, her body felt like it needed it. A primal urge to just keep fucking him, letting him blow his loads deep inside her. Needless to say, the thought of seeing Mike again really made her pick up the pace with going to change.
